How to receive UART data with checksum value in stm32l4r5zi MCU?

Is there any available drivers/libraries to send Data from STM32F4 to TJA1102 100BASE-T1 dual/single PHY for automotive Ethernet using MII ?

Is it possible to use UART with more than one buffer?

I have no idea why this code is not working. I am sending chunks of a file with UART followed by short instructions of 2 bytes to tell the MCU whether another chunk is coming or to start playing the file.The MCU receives the first chunk without an is...

Continously Receiving UART Data and Transferring to DMA without Generating Interrupts With Variable Length Data on the STM32L475RE

I am working on a portion of code that handles some UART messages that come in periodically from an LCD. The reception of a message over UART from this screen will generate a response based on the parsing of the message received.It is part of a large...

Is an STM32 compatible with TDM8 ? And if yes, with 2 streams of TDM8 in and 2 of TDM8 out ? Or is there any other solution ?

Hello, I'm quite new to STM32 (although I've been looking at it for more than a year) and I'd like to use it for a project that has been going on for somthing like 2 years now. It's a digital audio mixer especially designed for portable use for movie...

STM32L0xx saw tooth current in permanent run mode

Hi,if I never call any wfi / wfe and run my stm32l0xx mcu in permanent run mode, I got a sawtooth shaped consumption current. In normal mode, where I call wfi, this is not a issue, but I'm curious.Any ideas where this comes from?Thanks & best regards...

Trigger DMA for SPI based on Timer interrupt

Hello,I need to sample an ADC at 20ms using SPI. I setup a timer interrupt to do this, but I would like to fill a double buffer at SPI_RxHalfCplt and RXCplt.My timer seems to be working correctly, however the Rx Half Complete Callback is being Called...

Data to Store Array

I keep the important information in 32 byte. But every block have 32 byte .There are more than 300 block and every block have 32 bytes of data. So I've 32*300 byte data. How can I keep in the RAM successfully. Sould I Keep with array (uint32_t) or po...

PLL startup problem

I'm using STM32F105RBT, and I'm finding that, in certain circumstances, the phase locked loop is failing to become ready.1) Boot (sysclk = HSI @8MHz)2) Set PLL with source=HSI(div2) and multiplier=93) Enable PLL4) Wait for PLL ready (waits forever he...
