Hi,I'm trying to resolve a issue I see occasionnaly where my USB CDC-ACM device fails to be detected by Windows/Linux host as it is not responding to the first device descriptor request until the system is fully reset.The scenario:STM32U575 (can repr...
Hi,I'm using SPI to communicate between two micros - one F103 (master) and one H750 (slave). The data communicated will be vastly different in purpose and size (e.g. from simple requests to firmware image download) and so the designed protocol necess...
I have configured the STM32U575 UART baud rate to 115200. I tried to send the data from external utility tool with baud rate 9600, since the baud rate is wrong, there won't be any communication.Now if try to change baudrate to 115200 then also commun...
Hello,I am trying to optimize a function for a basic FIR filter on a STM32H743. This is the function:inline float_t FIRFilter(const float_t* inputBuffer, const float_t* firData, const uint16_t size, const uint16_t currentBufferIndex) { float_t outpu...
Hello,We use a couple of different STM32's in our products and update them over USB via built-in the DFU bootloader.I noticed that:for a STM32G491, the iProduct descriptor reports "DFU in FS Mode"for a STM32F302, the iProduct descriptor reports "STM3...
Hi,We are starting a LoRaWAN project here at the company and we are going to use the LSM110A module that has the STM32WLE5CC.I would like to know if you have a LoRaWAN stack for this ARM processor (STM32WLE5CC), or a video demonstrating how to start ...
Hi Team we need CMRT_6.31, could you provide it to me?email: dqi@lantronix.com
Hello, I'm looking for an mcu that can both do USB DFU programming and has and external crystal which there aren't many cheap available now (or would drop the external crystal requirements if I'd get convinced otherwise because I want it as stable as...
Hello, everyone. I hope you're doing well.my work at this time: https://github.com/MarginallyClever/Daisy-Driver-2.0-firmware/commit/465ec3dbeb831ee2f49fd6a6648da8fd7377a56aMy code is written in Arduino 2.2.1 with https://github.com/stm32duino/Board...
The problem you are experiencing with your STM32F407IGT6 board is that after programming the firmware and using Ethernet (UDP) communication, if you power it off and then back on, the Ethernet communication doesn't work. However, if you press the Res...
