Resolved! Flash Loader Demonstrator cannot open port
I have a Win10 notebook computer. When I run the Flash Loader Demonstrator, it correctly finds the com port being used (the only one) but when I click 'Next' it always says "Cannot open the com port, the port may be used by another application". Thi...
SDIO fail to run over freq > 2MHz
Hello Everyone !I am using 4bit SDIO over STM32 F4 Nucleo board (STM32F412ZG).I am facing issue when running higher SDIO_CK clock.When I use smaller 'Div' value (higher freq), it does not produce correct clock and in stead produces very small clock i...
Resolved! CubeMX / STM32L476 / NAND Flash
I'm trying to experiment with a NAND flash connected to a STM32L476VG and I'm using CubeMX to set everything up. No matter what I do, I cannot get CubeMX to show me a NAND flash as an option for the FMC. The options are LCD, Muxed NOR and Muxed PSRAM...
STM32H743 nucleo won't work in USB OTG FS
Posted on November 07, 2017 at 10:49Hello,I am working on a STM32H743 – NUCLEO 144 and need to use OTG_FS device only option in CDC mode.I generated a project using the stm32cubeMX and have defined: SYS – Time bases : TIM1USB DEVICE – class f...
Resolved! INTERNAL TEMPERATURE SENSOR: Reading false value (STM32L152RE)
Hello all,I am working with the STM32L152RE and want to read out the internal temperature sensor of the mikrocontroller. My code is the following:#define TS_CAL1 *((uint16_t*) 0x1FF800FA) // 30 °C#define TS_CAL2 *((uint16_t*) 0x1FF800FE) // 1...
Resolved! How are VDDA, AGND and VREFP connected to the MCU-Pins on NucleoH723ZG?
Hello everyone,I am using the NucleoH723ZG board and I'd like to use the internal reference voltage for ADC-purposes. Initialising the VREFBUF... VREFBUF->CSR &= ~VREFBUF_CSR_VRS_Msk; //Voltage Reference set to 2.5V VREFBUF->CSR &= ~VREFBUF_CSR_HIZ_...
How can I connect an inductive sensor (with an M12 connector) to my STM32F769I-DISCO?
Hello everyone! I have to connect an inductive sensor to my STM32F769I-DISCO in order to count the rising edges of the signal which will correspond to the use of sheets of paper by a machine. So, especially if you have already done that, I would need...
Is it possible to intercept CAN messages between CAN Device and its CAN Transceiver
Hi, Is it possible to add STM32F407VET6 which has 2 CAN connections between CAN device and its CAN Transceiver?I want filter some of the messages from device receiving them and forward the other. Can I do that without using Transceivers and just inte...
Resolved! STM32F, L, W, H, U series version keyword.
Hi, guys.STM32 have a several series STM32F, STM32L, W, U, H..., but what is the meaning of F, L, W, H?(like a F: fast, L: large, H: high spec...?)I think this work is just an version number, someone know is it?Thank you.
