I'm looking into calculating the timings for the brk filters for the TIM1 periphery. Mentioned there is the "tim_ker_ck" and the "tim_pclk" respectively.I cannot seem to find any information on where these come from.The clock tree in the RM says that...
Hi community,I build and program both CM without error and debugger configuration as in the AN5361 .The Nucleo- runs with maximum frequency 480 MHz, and Power supply: HAL_PWREx_ConfigSupply(PWR_SMPS_2V5_SUPPLIES_LDO); __HAL_PWR_VOLTAGESCALING_CONF...
Hello,I have a very strange behaviour with the I2C bus of a STM32G431.I try to communicate with a MLX90393 of Melexis. I had some problems to get the measurements, after a Start measurement. The MLX90393 returned an error code. So I checked the signa...
hi come across these code using register programing, STM32F411 Nucleo bd, anyone can advise how does the (AF07<<4) and (AF07<<8) relate to UART2 PA2 & PA3? please advise.. #define AF07 0x07 GPIOA->AFR[1]|=(AF07<<4)|(AF07<<8); //ALT7 for UART2...
Hi,I have read thoroughly RM0454, STM32G070CB datasheet and AN4187 in order to understand how to configure the DMA and DMAMUX in order to feed the CRC peripheral with FLASH data using the DMA (with CPU it is working but way slower than expected).I do...
however, pwm1 doesn't output pulses. I think timer1 stop comparing output if calling Stop() function. Anyone has idea to implement this? Thank you.
I want to design a baord with stm32h7b0zbt6 with extranal sdram chip W9825G6KH-6. I get PG15 with FMC_SDNCAS alt func in datasheet as below:But when I looked the PG15 alt func config I get as below info, I could not found an alternate function number...
Hi ST Community members,I recently encountered a problem with the ISM43341-M4G-L44-SPI WiFi module mounted on the STM32H7BI3-DK development board. Here are the details of the issue:Context:I updated my Cube Programmer, CubeIDE, and stlink firmware.Wi...
Hi all, for some reason I have massive trouble making an SPI write function for a w5500 chip. I followed various threads to make this code which I also did for the solution of my problem. Sadly it hasnt helped yet. Thats why I am making my own post n...
I made following two versions of the same software to process DMA data, one using floats and the second using uint32_t to try run faster, but as a surprise the first one run faster: //161 void process_data_ADC1() { float samples1=(2.0f/(float)ADC_B...
