 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

RC14 also seem to cure an issue i had with RC12. SETTICK timer interrupts stopped on a random basis. RC14 now running > 12 hours without any issue. Environment is WebMite without any options set (except autostart on). Regards, Gerald 73 de OE1HGA, Gerald |

UPDATE The current release SDK (V2.0.0) has a bug in the timer alarm system that causes the routine 1mSec timer that is used throughout MMbasic to stop under unknown circumstances. This only happens after a period and there are no obvious causes. The development version of the sdk purports to have fixed this bug BUT appears to have completely broken USB host functionality. RC14 doesn't work properly when a USB keyboard mouse or gamepad is used. RC12 was built with SDK V2.0.0 but included a fix that restarted the timer if it stopped. This worked in all versions except the WebMite which it completely bu....ed My final frustration is that TinyUSB connects a mouse in BOOT mode. This is like the mouse functionality you see in the BIOS on a PC. This works as far as positioning and the buttons are concerned but does not support the scroll wheel. Is there anyone out there who understands USB enough to use a sniffer and find out what the USB host needs to send to a mouse to switch it out of BOOT mode? Google has lots of people asking the same question and no replies. AAGH!!!!! The only good news is that I've nearly got the USB mouse working in the in-built editor allowing cursor positioning and cut-and-paste using the mouse. |

Both PS/2 mice and USB mice need initialization to work with the scroll wheel. There are also several types of USB mice whose reports differ. I wrote earlier that there is a project where a person made his own library for working with USB HID devices for SDK 2.0 and TinyUSB 0.17 (like keyboard, mouse, joystick, gamepad) in which he solves this problem of parsing reports from different types of devices, including initialization of the scroll wheel of USB mice. I took part in testing it on devices. Please take a look at it: https://github.com/fruit-bat/pico-hid-host BTW: At the same time, you can ask him to port his ZX-Spectrum emulator to the PicoMiteHDMIUSB platform. He is a very kind and responsive person. https://github.com/fruit-bat/pico-zxspectrum PS: He also has implemented HDMI sound. Edited 2024-11-04 22:24 by javavi |

I looked at that code but couldn't find my way through it to where he does anything obviously different to me. My code in the CMM2 for the PS2 mouse enables the scroll wheel but sending a USB report with the same code sequence on USB does nothing |

It may be initializing the mouse somewhere in the main program, but the mouse scroll wheel works fine. Let me remind you again that, like joysticks, there are at least two varieties of USB mice with different response reports. |

Another funny effect found just by "incident" (typo) on WebMite RC12 upwards setpin gp25, dout results in Error : Pin 43/hijklmnopqrstuvwxyz[\]^_`abcdefghijklmnopqrstuvwxyz{|}~ Different illegal pins give different text after the / Did receive a properly formatted errormessage at least in RC11 ...

V6.00.00RC15 PicoMiteRP2040V6.00.00RC15.zip PicoMiteRP2350V6.00.00RC15.zip Revert to sdk2.0.0 with check/correction for millisecond clock stopping Fixes validation of pins in WebMite New functionality: HDMIUSB and VGAUSB (RP2040 and RP2350) If you start the editor with a mouse plugged in and are editing in mode 1 with colour coding on you will see a character highlighted with red on a white background. This highlight can be moved using the mouse. In normal mode Left clicking on the mouse will move the edit cursor to that position - same as using the cursor keys Right clicking the mouse will enter mark mode (cut-and-paste) with the cursor positioned where the highlight was i.e. right click = F4 Clicking the scroll wheel will paste the contents of the cut-and-paste buffer at the location of the highlighted character i.e. wheel click = F5 In mark mode (cut-and-paste) Left clicking on the mouse will move the edit cursor to that position highlighting characters from the mark position to the highlighted position - same as using the cursor keys Right clicking will cut from the mark position to the highlighted position storing the cut characters in the cut-and-paste buffer and exit mark mode i.e. right click = F4 Clicking the scroll wheel will copy from the mark position to the highlighted position storing the cut characters in the cut-and-paste buffer and exit mark mod i.e. wheel click = F5 NB: on occasion when exiting cut-and-paste a single character may be incorrectly colour coded. This is benign and will correct itself when that line is redrawn Edited 2024-11-06 00:43 by matherp |

I'd just started a settick test, after reading about an issue, when I saw RC15. I updated my RPi Pico 2 and ran my normally rock-solid "settick 1" routine. It runs for a few seconds and then:  Oh wait....it's also the first time that I tried 396MHz..Dropping back to 378MHz to test. Edited 2024-11-06 01:38 by PhenixRising |

False alarm...My Pico-2 doesn't like 396MHz |

Still early testing but so far both PicoMiteHDMI using pico2 board and PicoMite at 315MHz and 150MHz using PGA board pass the XMODEM send tests with MMCC I will do more tests but looking good so far! Jim VK7JH MMedit MMBasic Help |

External PSRAM for PicoMite  Is it possible for PicoMite to combine the connection to Pico of an external SD card and the SPRAM memory on one SPI bus? Make the choice of access via the Chip Select line, for PSRAM it is inverted, which means it is available when there is no access to the SD card. What are the considerations for this? |

if psram is cool then why it not implemented commercial pico boards? |

We now know that Pimorini's PSRAM is slow on a QSPI bus. It'll probably be slightly faster than paper tape storage if you use a single SPI channel. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

javavi, A PS-RAM as a external memory device can technically function on the SPI bus. But you would need to treat it as such. The SD card speed (clock speed) is in the 5-16MHz range. The PS-RAM would need to use similar, but it is 1 bit databus. The RP2350 boards that have PS-RAM use the memory chip at somthing like 60MHz with a 4 bit wide bus. That gives a datarate that is around 20x faster. This is the same bus that the flash is on. Additionally there is (hardware inside the RP2350) a caching mechanism attached to the QSPI bus. So yes, technically it is possible, but it may be better to buy a device that has PS-RAM on board. so you can use it in a transparent way, and it is much faster.

Volhout, Thanks for the detailed answer! I just know that the emulator guys use PSRAM in single-bit SPI mode in their emulators of retro computers on Pico (RP2040) and this memory allows them to expand the RAM of emulated devices, such as ZX-Spectrum 1024k on Z80 @3.5MHz with memory page switching. True, this works on PIO machines at a data rate of up to 133 MHz. Yes, I am aware of the expanded capabilities of working with PSRAM of the new RP2350 chip, but unfortunately there are no available modules with installed memory yet. I don't understand why it was impossible to make a landing place on the bottom of the reference board. Regards, javavi. Edited 2024-11-10 06:14 by javavi |
