STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
I am working with Cube, over HAL library, implementing a DMA mem-to-peripheral interface in double buffer mode.STM32H755I have two inputs: EXTI0 as a trigger, and LPTIM2 as a clock.DMA is configured to output a byte through GPIO D0 through D7I need t...
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...
Folks,Once I had my SD card working, I went to add in the Formatting option. When I enabled the format SD Media option in the FileX config, it generates this below, even though my settings are set to FX_ENABLE_EXFAT. Shouldn't this auto-generate the...
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...
