I am using STM32H747I-DISCO discovery kit. I want to use I2C4 in the kit but clock is not generated in scl. I am using pin D15 as SCL and pin D14 as SDA of CN5 connector of discovery board. According to the user manual of discovery board D15 is conn...
The ui framework generate an image section of the framework, there is no way to place it to internal flash, so I must copy it to a file and transform it to ext flash.So do you know how to generate the binary file?
I'm a biginner on embedded programing and facing an I2C communication halt issue when I put HAL_I2C_Master_Seq_Transmit_IT() in HAL_GPIO_EXTI_Falling_Callback(). STM32CubeIDE: Version: 1.6.0, Build: 9614_20210223_1703 (UTC)Target board: NUCLEO-G031...
Hi,I have connected three channels of the SDADC in the STM32F373 with an external voltage reference of 1.225V. The selected mode of the ADC is Single-ended zero-volt reference mode, and i am reading these channels using the "injected conversion" as i...
I have mastered and timed two timers and can produce both pwm and not pulse. But my problem is that there is no dead time between pulses.Can you suggest a way for me to have an option like ch1ch1n in other timers that have dead time?
I actually need 6 Plus. (3 pulses (not) are other pulses). I have generated 4 pulses with two timers 1 and 8 and I need to generate two more pulses, but I can not produce dead time with advanced timers. I have used advanced timers and I need to have ...
In STM32F437 data sheet it says VDDA - VREF+ < 1.2 V.Is that a "global" limitation or just a working limitation?If VDDA is 3.3V and VREF+ is 0V, can that harm the chip, or is it just that the conversions don't work right?
Hi all,I am using the Delay function as follows.static void Delay(volatile int d) { d = d*20; while (d--) asm volatile("NOP"); }However, sometimes when adding printf code, Delay function becomes slow.So, when I analyzed the cause, I was able to...
I'm having trouble making use of SDRAM (external device memory) on the STM32H743 EVAL2 board. Specifically, I'm trying to make use of FMC SDRAM Bank 2 (Region: External Devices) to store a large array. Here are code snippets that I have added/modifi...
Hi, I'm curentlly in the process of switching to a STM32L412 from an STM32F3 on a custom design and I'm having an issue with the UART bootloader. The bootloader worked as intended on the F3 chip but on the L4 chip I can't write to the chip. Everythin...
