I am working with the STM32F760I-EVAL board and caching (SCB_EnableICache() and SCB_EnableDCache() are called) and MPU (MPU_Config() is called) are enabled. I am using DMA with SPI and if I transmit data, HAL_SPI_Transmit_DMA, I need to call SCB_Clea...
I did interfaced STM32l151 with ENC424J600 using SPI , But know i don't understand how to make buff of data to send over ethernet .I did tried some stuff but all says incorrect sequence or frame, sometimes it shows LLC .I am stucked in here please he...
I am trying to figure out the details of how to jump to the internal bootloader on STM32L475. The following code works just fine on the STM32F405, but similar (updating the address obviously, which is actually the same) will not work on the L475.ldr ...
In the M0 I used this code to get the current pointer position U1RxBufferPtrIN = U1RxBufSize - huart2.hdmarx->Instance->CNDTR;but on the H7 this register is not available.How can I find the current Rx pointer position from the Uart DMA controller...
Hello to all.I'm trying to setup the STM32F746-Discovery board for audio transmission.For the audio transmission it is important to use double buffer mode.I'm using the HAL and the stm32746g_discovery_audio.c and wm8994.c filesThe LISR register signa...
We are trying to configure a STM32H743 device to use 8 PDM microphones. According to the manual, this should be possible.In addition, up to 8 microphones can be supported thanks to an embedded PDM interface.The SAI can work in master or slave configu...
I use the internal EEPROM of my STM32L071 to store a Device Configuration. All Testing with writing and reading my Structure or just single Elements of my Structures are working fine.After the Device runs a while, I needed to store an updated Configu...
Posted on October 23, 2016 at 14:55 Hi. I'm looking at following register in manual: OTG_FS device IN endpoint transmit FIFO size register (OTG_FS_DIEPTXFx) (x = 1..3, where x is the FIFO_number) It has two parts: Bits 31:16 I...
Good dayI have made an audio spectrum analyser using the STM32F7 board described in the title. Using the ADC and an external board which made sure there was a DC offset to prevent going out of the ADC voltage specs i was able to read audio signals. U...
Hi, In last (and former) STM32H7 series CMSIS headers, there is some miss-spelling in SYSCFG which is replaced by SYCFG (-s).Regards,Julien FAUCHER.PS :Here is the output of a grep command : stm32h743xx.h:18316:#define SYCFG_PMCR_EPIS_SEL_Pos (2...
