[STM32L4] [FreeRTOS] [USART3] Some of the Rx Interrupt are getting missed when entering Sleep Mode
Posted on August 01, 2016 at 14:01Hi,I am using STM32L4 with FreeRTOS.I have configured the USART3 Rx as Interrupt HAL_NVIC_SetPriority(USART3_IRQn, 4, 0) and am using the Tx as Polling.Without entering the SLEEP mode, if I send data on USART3 from ...
STM32F7DISCO: is it possible to get the firmware for ST32Link
Posted on August 01, 2016 at 23:20Hello,I'm using the stm32f769i-disco board. There is a onboard st32link debugger which makes possible to flash/debug the board via USB.Can I replicate this part on in my design? If i put the same ARM for stm32link i...
STM32CubeMX: not all pins are shown
Posted on July 29, 2016 at 17:46I'm using STM32F746ZGT6 device.I select SPI2 and software gives me 27,28,69,73 pins.But there are other pins that can be used for SPI2.73,74,75,76 for instance.How to make software to show other sets of pins?Thanks

Posted on July 19, 2016 at 17:32Hi,I'am starting a new project and I will need to interface the STM32F4-discovery with a camera ( 5mp ),can you suggest me a DCMI camera module with 5mp resolution
Delay with Center Aligned PWM triggering an ADC conversion
Posted on August 01, 2016 at 16:28Hi,I’m using a stm32f103 to generate center aligned PWM on which i have synced a dual regular simultaneous injected mode ADC conversion.I’m using TIM4 as source of the PWM signal and, to launch the ADC acquisition a...
Bug in the en.CD00251732.pdf manual
Posted on July 29, 2016 at 23:46I guess on page 30 in the manual ''en.CD00251732.pdf'' is a bug: the memory map for the I2C2 should be 0x40005800 instead 0x40005C00. 0x40005C00 must be ''reserved''.
I2S microphone, sample rate
Posted on August 01, 2016 at 14:14Hello.I use an example from CubeMX - Audio_playback_and_record. He works at STM32F4-Discovery board - playing and recording a sound (wav-file). By default the sound recording goes with sampling rate of 16000 Hz, but...
stm32f4xx_hal_i2s_ex seems incomplete - doesn't work
Posted on July 08, 2016 at 18:04I'm developing an audio application using STM32F427, using I2S port 3 in ''full-duplex'' mode to interface to ADC and DAC. Trying to use the non-blocking-interrupt method, as I don't want to use DMA and there are seve...
Problem with STM32F427 ethernet
Posted on August 01, 2016 at 14:02Hi, I'm working on a project running on STM23H427, using LwIP and FreeRTOS, with original basic code generated by STM32Cube. My application needs to send small UDP packets at 4mS intervals. My problem is, that after...
