Hi,I want to sample 9 channels with 1 ADC, using DMA in circular buffer mode with continuous conversion. My callbacks of conversion (like HAL_ADC_ConvCpltCallback or HAL_ADC_ConvHalfCpltCallback) are not triggering, the sampling seems to never start....

Hi,I'm using extended ID for my CAN bus. I want to filter ID 0x12.My code is working well when I receive an extended ID frame with containing the ID 0x12. If the received ID is something else than 0x12, the FIFO callback isn't triggered.CAN_FilterTyp...

Hi,I'm looking for a dual ethernet examples from ST, but I couldn't find any.I've seen that there is no STM32 with dual ethernet interface.So I look among the 3-port switch (KSZ8863 etc) but unfortunatly I cannot found any reference design by ST. Als...

Hi,I am currently developping a custom bootloader to flash my app with STM32H7A3ZIx / SDMMC / FATFS with DMA templateIt fetch a binary (*.bin) from an SD card, read maximum BUFFER_SIZE (=8192) and stores it in a uint8_t RAM_Buf[BUFFER_SIZE] array (8K...

Hi,I've just updgraded from TouchGFX 4.17 to 4.18. I'm using STM32Cube IDE 1.6.0.After regenerating the project from TouchGFX 4.18, when I build there is an error:"../TouchGFX/generated/videos/src/keil/Videos.s:1: Error: bad instruction `generated by...

Found the culprit. The init (done by CubeMX) should have DMA init before the ADC.MX_DMA_Init(); MX_ADC3_Init();To change the init generation go to MX editor, Project Manager > Advanced Settings > Generated Function Calls and move the ADC init under t...

thanks clive, I hadn't thought about it. now it works with filtering/masking the IDE bit:sFilterConfig.FilterIdLow = 0x12 << 3 | 0b100; sFilterConfig.FilterMaskIdLow = 0xFF << 3 | 0b100;here's a pic that helps to understand :

that's it ! guess I'll buy new glasses. thanks :thumbs_up:

In the mean time I cast into an array this way all the digits are printedchar array[20]; sprintf(array, "%.9f", 0.123456789f); Unicode::strncpy(textArea1Buffer, array, TEXTAREA1_SIZE); textArea1.invalidate();
