Hi, the 18F47J53 needs the following configuration settings to make USB work with a 16 Mhz crystal. The CPU clock speed is 48 Mhz. Capture21-10-2019-20.06.20.jpg Also following init code has to be added (you cal leave out the "default" lines if you want): Capture21-10-2019-20.02.13.jpg The total osc...

Hi, I have something, I do know anymore where it came from: The library: unit Nokia_3310_5110; // interface procedure InitLcd; procedure SetContrast(Contrast: byte); procedure Lcd_clr; procedure Lcd_command(command_: byte); procedure Lcd_char(data_: byte); procedure LCD_Text(var Text: string); proce...

Hi, I am working on a more flexible HID Host library. It will be able to also handle devices with an other endpoint size than 64 (e.g. keyboards and mouses).
So, a little patience...

Hi Jose, I did some calculations with raw writing of a sdmmc cards, see https://forum.mikroe.com/viewtopic.php?f=194&t=63554&hilit=speed&start=15#p253234 for the measurements. This means in your case: Your SPI clock speed is 62.5 Khz (4 Mhz div 64), which means your SPI writing will be 160x (10000 K...

Hi, - do you never re-init SPI1 at high speed? - what is the MCU clock speed set in the IDE's 'edit project'? - is the SDMMC card nearly full during the test? Why do you disable also the 4x PLL? <SETTING5> <NAME>PLL x4</NAME> <DESCRIPTION>Disabled</DESCRIPTION> </SETTING5> If you re-init the SPI to ...

Hi, this problem is even older: https://forum.mikroe.com/viewtopic.php?f=172&t=56173 For PIC32MX270F there are other similar problems: https://forum.mikroe.com/viewtopic.php?f=164&t=66186&start=30 mikroe team should really spend some time fixing all these constants. :) Thanks VCC. It is indeed a pi...

Hi, the _FLASH_ERASE value, defined in the FLASH library seems to be wrong for some PIC32 types (e.g. in my case the P32MX250F128B). They have a flash erase block size of 1KB in stead of 4 kB (e.g. for the P32MX795F512L). Extract from the P32MX250F128B datasheet: Note: The Flash page size on PIC32MX...

okay, so what kind of HID device am I supposed to connect in order to at least see USB_HID_Device_Ready boolean set to TRUE? Hi, I do not know it there are any "generic" USB devices commericially available (I doubt it), you will have to make one yourself (with e.g. a PIC). In the mE USB HID device ...

Am I the only one in this case?

Hello to everyone. I'm trying to make some initial experiments to build a minimal USB Host system, HID device only, based on a PIC24FJ64GB002. I installed the PIC24F USB Host library available on Libstock, courtesy of Dany. Built a bare minimum board with PIC, USB Socket and a 2x16 character LCD. T...

Hi, program Empty2; { Declarations section } begin { Main program } OrgAll(0x9D000000); end. How is it possible that the (almost) empty program above generates a "not enough ROM space" error? I use mP for PIC32 3.6.0. The error is not there when I leave out the OrgAll statement. In that case the cod...

Same problem here... Very annoying. I think this popped up after an automatic windows update.

Files have also a fixed place (used sectors) on an sdmmc card, so the wear will be the same when writing to a file as when writing sectors directly. Of course in the latter case the speed will be much higher (no FAT overlay).

I was informed (thanks Ed) that the MikroPascal32 4.0 compiler has the same problem (and the same solution) as discribed in this thread: viewtopic.php?f=86&t=69487.

The problem is still there with mP for PIC v7.2.0.
