Posted on June 30, 2017 at 12:29Hello,I have a strange behaviour in a bit complicated setup:This is my setupa number of concatenated timers create a periodical burst of 4 pulses, 70 µsec appart, bursts are 2.5msec apart. These pulses trigger a DMA ...

Posted on April 07, 2017 at 15:09Hello,I am using STs USB CDC VCP stack on a STM32L151.Now I have the special case that some time I come to initialize it a second time, ie call MX_USB_DEVICE_Init(); though it is running. This does not take away the ...

Posted on January 09, 2017 at 15:23Hello,I am looking for a way to generate a CRC after compilation and add it to the hex file at a specified address so that it can altogether be programmed to flash and at runtime can be compared to a value calculat...

Posted on July 20, 2016 at 15:31Hello, I use STM32L1xx ADC in scan mode with DMA with these settings: ADC_CR1_SCAN set ADC_CR2_CONT cleared ADC_CR2_DDS and ADC_CR2_DMA set ADC_CR2_EOCS cleared I scan 4 channels after trigerering with ADC_CR2_SWSTART...

Posted on July 19, 2016 at 16:53Hello, I use STM32L152 on STs Nucleo board. I created a small progtam to test ADC. It is mainly a state machine that steps forward every 100msec, repeating after 10 steps. In step 1 I start a conversion sequence cons...
