Hi all,I was trying to write to the codec (WM8994) I2C3 in the STM32F746 Disco board without luck. After trying a few things and looking at the data on my scope I realized the codec was not acknowledging the address. The problem is I was using 0x68 (...
STM says: OCTOSPI can generate a "regular SPI" transaction. But is not true:A "regular SPI transaction" means actually on OCTOSPI: a half-duplex SPI transaction (using just IO0, but for both directions).I you want to generate a "regular" SPI transact...
Hi, when configure MCU to deep sleep mode as the low power mode, it seems okay when debugging. But, when only power up STM32C0 by just connected its vcc and ground, it do not enter its interrupt. How can I solve it?My project goals are to achieve low...
"I used the STM32F746ZG to read the current from an ACS712 sensor, but the problem is that the ADC is not stable. I tried using an STM32F466RE to measure the same current, and this time the ADC is stable. I don't understand why, despite the ADC chara...
I've tried to see if I can get away with using just one bank address pin for a 4-bank SDRAM (IS42/45S16160J). My understanding is that this would half the addressable memory, as I could only access two banks instead of four.In the STM32H7 user manual...
Hello everyone,I intend to migrate an LPC development to the new stm32h5 family, I find the versatility that its flash offers very interesting. Being able to separate a set of memory into two blocks to run the main program without the need for an IAP...
Using the STM32H747I-DISCO, I am having problems getting SPI working at all.I am using SPI5, to allow connecting an X-NUCLEO-NFC08A1 directly via the Arduino headers.I do not see any data on the SCK line and HAL_SPI_Transmit() always fails.Looking in...
Hello everyone,we are developing a product using STM32F413.We got a new requirement, that the chip needs to activate ROP level 1. We want to do this from firmware code, if possible.I noticed that after flashing my firmware and running the code that a...
I'm finding difficult to get the value from the channel that i configured of a regular channel with stm32l412 microcontroller. where I'm not getting the EOC interrupt enabled in ADC_ISR register. and When I tried to get data from ADC_CDR register, i...
Hi,I have the following board : NUCLEO-F429ZIThe datasheet says that UART3 is the STLINK UART that can be used over USB.I configured this UART but when I try to receive anything from the terminal that is connected to the UART com port, I don't see th...
