Resolved! Does STM32CubeMX/HAL have the ability to configure the I2C_CR1's ACK bit on the STM32L151xx?
I am currently attempting to port a product's older firmware that used the Standard Peripheral Driver libraries over to using the HAL libraries for greater portability between different MCUs. I a currently using the STM32L151QEHx. In the older firmwa...
Bidirectional Line Termination - will just one resistor work?
I am designing a PCB for an ST micro MCU with external SDRAM.On the demo board, ST is using one series resistor termination for the bidirectional data lines. ST places this resistor at about 30/70% split of line length, where the resistor is 30 % of ...
STM32L431 ADC initialization problem
Hi. I have a problem with ADC on a custom board with STM32L431CBY with external 24 MHz clock. Everything (UART, SPI, DAC e.t.c.) works fine except ADC. Clock initialization:static void setSystemClock(void) { LL_FLASH_SetLatency(LL_FLASH_LATENCY_...
Compiler for STM3240G-Eval
Want to know the compiler for STM3240G-Eval Board.
HAL_I2C_Master_Receive_DMA not returning updated values.
Hi,I am using one I2C based peripherals with Interrupt enabled.While using "HAL_I2C_Master_Transmit" and "HAL_I2C_Master_Receive", it seems to work properly with ISR.But, when I am using the following I2C_DMA:HAL_I2C_Master_Receive_DMA(&hi2c4, MPU_DE...
What the max ADC sampling Rate when using STM32H747 M4 Core? Does it same as M7 ?
Hi Everyone,I found the document(AN5354) talk about 16bits ADC Max sampling Rate and I verify that on M7 Core. It's correct.My implement include Total 3 ADC 3 Channel(one channel per one ADC) run 1Mhz Sampling rate and using DMA with timer trigger Bu...
STM32F107 Quadrature encoder
Hello,Regarding this post I am able to read my encoder value correctly. // STM32 TIM3 Encoder Decoder (PC.06:A PC.07:B) VLDiscovery - sourcer32@gmail.com #include ''stm32F10x.h'' #include ''STM32vldiscovery.h'' /**********************...
How to program an STM32H73x to put it in low power, that it consumes as little as possible, and that it can wake up with a GPIO?
I am using an STM32H735G-DK board to do my tests. My goal is to toggle a LED on PC2 every time I wake up the MPU when I put PG5 to ground. Once the LED is toggled, I want the MPU to go to the lowest possible power consumption. Does anyone have an exa...
