Thank you for the new I2C peripheral in STM32H7, this really looks VERY much improved compared to STM32F4.Can the STM32H7 I2C in master mode somehow "free the bus" in case of "stupid slaves holding the SDA line down"?It is a quite common problem of I...
Posted on June 28, 2018 at 13:29Hi all,I'm trying low power modes of the STM32. I've noticed that HAL_PWREx_EnterSTOP2Mode synopsis mention that: * The voltage regulator is set in low-power mode but LPR bit must be cleared to enter stop 2 mo...
the MCU stm32L011F3 has only 8k flash ,and without standard peripheral library, only HAL and LL library, as i know, the Optimization of HAL is lowest all of them, and LL driver is little Readiness,can any one tell me, is that the HAL driver can exec...
We use STM32F746 discovery board and run stm32f7 as spi slave with nss as sync signal between each byte. The master drives nss, clk and mosi pins. Clock is 250khz and processing is done in interrupt. Every 100ms 1 byte is transferred. Sometimes the s...
Im trying to set up a KISS FC and i can not get it to connect so i followed some tutrials and used the software but nothing is showing up so i cant complete any of the tutorials.
I am porting a firmware from STM32F2/F4 to a H7 (STM32H743IIT6) platform on a custom board. There is an SST26VF064B-104I/SM flash on the boards with custom drivers with FAT FS file system driven by SPI and DMA. It works perfectly on older boards sinc...
Reference manual RM00385.1.1 Independent A/D and DAC converter supply and reference voltageOn BGA 64-pin and all packages with 100 pins or moreI need a bit of clarification on correct voltage ranges for VDDA and VREF+:2.4 V ≤ VREF+ = VDDADoes it mean...
Hi,I am receiving the STM32L010 NUCLEO board tomorrow and was trying to set up my dev environment. However, I cannot find the STM32L010 in the Keil Pack Installer.Error Message: "Cannot select device(STM32L010RBTx:STMicroelectronics), Device not foun...
Hi! I don't know it is the right place to ask this. I want to use the X-NUCLEO-CCA01M1 and CCA02M1 shields with NUCLEO-L496ZG but I do not find any information about it. The NUCLEO-L476RG and L469ZG's MORPHO pinouts are almost identical (the relevant...
Need to generate a repeating waveform with external SPI 16-bit DAC.Using a table of values in memory, repeatedly loop through table outputting values to DAC.Delay between outputs is constant. No glitches at repeat!DMA only (no interrupts).What's the ...
