I'm busy with a USB to Ethernet implementation using the ST USB library and LwIP.When I send a packet to the host (Data IN) that came from the ethernet interface, I know where is the end of an ethernet frame send a zero length packet (ZLP) accordingl...

I've been working on making my SD SDIO card access non blocking. My implementation is a derivative from the standard ST SDIO SD driver (stm324xg_eval_sdio_sd).I'm using Protothreads (basically a state machine) to make the SD SDIO calls non-blocking a...

Posted on May 07, 2014 at 02:56I'm using the STM8L101F3 with IAR. I would like to set and clear the Activation level bit. There is no library function to access this and I'm not sure how to access this register from code. Looking at iostm8l101f3.h, ...

Posted on June 06, 2013 at 00:05All my timer interrupts are working except for TIM1. What could be wrong. I'm using Keil ARM with the STM32F013C8. Here is my startup code: EXPORT WWDG_IRQHandler [WEAK] EXPORT PVD_IRQHand...

Actually, the logic is the same as the IN transfers. A transfer is considered to be complete if one of these two conditions are detected:A transaction with less than max-packet-size bytesA full length transaction followed by a ZLP

Anybody?

Well, I'm implementing CDC ECM and windows does not have a driver for this. Unless you know of one that I can modify.So I'm testing on an Ubtuntu VM. Still CDC ECM.Ubuntu detects the network connection and I can ping the STM32. I've also implemented ...

Ok, found the issue. There was another disk access when the thread yielded.

Posted on March 23, 2016 at 22:09That worked when the system loader was enabled. When I booted from flash again I was still unable to program the flash. I then realized the PLLDIV was to low and the system clock was too high. Preventing me from prog...
