Posted on October 18, 2015 at 23:29Hi all,lost one day finding that this line 259 from stm32l0xx_hal_gpio.c is missing some braces:bad (current):temp &= ~((uint32_t)0x0F) << (4 * (position & 0x03));right (should be):temp &= ~(((uint32_t)0x0F) << (4 ...
Posted on October 22, 2015 at 11:13Hi, thanks for your code .but I found that when transmit data use HAL_UART_Transmit, the lock of uart api will cause HAL_UART_Receive_IT can't receive data.how to slove it?

Posted on October 20, 2015 at 22:05Hello could you please help me with my question about backup SRAM in STM32F427? I have design, where I am using voltage regulator for VDD and VDDA - 3V0. As backup I use batery 3.2V connected to VBAT pin6. My qu...
Posted on October 22, 2015 at 00:24Good day everybody, I'm having an usual problem on STM32F407 SPI. I'm using a STM32F407 discovery board with a custom made breakout board (SPI2 pins used are PB13, PB14 and PB15 and are connected to a AD7190 AD...
Posted on October 21, 2015 at 22:02Hello could ypu please explain me how can I check from Order number of STM32F427VI which revision (HW revision) in this chip? In datasheet I can check, that for STM32F4xxx exist several HW revisoon of silicon chip:...
Posted on May 22, 2015 at 11:33Hi,help me please to set up the SAI correctly.I need a mode I2S standart, 32-bit frame, 24-bit data. I configured my code: hsai_BlockA1.Instance = SAI1_Block_A; hsai_BlockA1.Init.Protocol = SAI_FREE_PROTOCOL; hsa...
Posted on October 10, 2015 at 17:31 Hello, I've the following configuration on my STM32F4: - ADC with DMA triggered from TIM3 - EXTI0 triggered fromGPIO PA00 - EXTI1 triggered from GPIO PA01 The interrupt EXTI0 and EXTI1 s...
Posted on August 27, 2012 at 20:01Is there a way to tell a TIMer on STM32 chips to do some number of steps and automatically stop after finished (and give an interrupt)? I can do it now with a counter in the ISR but a few pulses slip out before I c...
Posted on October 20, 2015 at 15:51Hi, all. Could you please recommend the best way to do that using STM32 Timers? Input signal is a 5-10 kHz 3V sine-wave, and high-stable TCXO 12 MHz is used for MCU clocking. Measurement should be done with 1E-3 H...
