Hey.Im using adc dma to transfer data from adc to memory. After each sequence of conversion I need an interrupt.My first question is that is using dma in my case something useless?My second question is that after adc sequence of conversion interrupt ...
I'm using STM32F103C8 and I have Bootloader at the start of flash 0x08000000 and Application start at 0x08008000. On powerup Bootloader start to perform basic functions and then jumps to the main application. Everything works fine but what about Boot...
Hello everyone,I want use USB port as USB OTG but firmware do not support this mode, instead Device and Host modes separately. Where can I read example of USB OTG driver implementation for free?Thanks in advance
My STM32H7 firmware was working and compiling fine before I upgrade my CubeMX firmware package from 1.3.0 to 1.5.0.It seems that the GPIO register struct has been changed and "BSRRH" and "BSRRL" members of the struct do not exist anymore! So my code ...
I use cube to generate DFU code and test its function. It is fine(device can enter DFU mode).But after I download APP code to 0x0800A000, then test again. Device can jump to app successfully but device cannot enter DFU mode. Device descriptor reques...
Hi All,I have a strange problem. I made a custom board with a stm32l151VETx and i cannot get the VPC to work. No device shows up in the device manager nor on linux under dmesg. However if I change the boot pins so that the internal bootloader starts ...
Hello.I'm trying to stitch-up the STM3210C LwIP TCP/IP Echo client example (my board) and STM324xG LwIP+FreeRTOS+NetConn example.LwIP, and netif config are the same as for Echo example (and previously I ran httpd-raw server with it).I was able to set...
I'm using the evaluation board ISC004V1 and using the GUI STUSB001 I noticed that you can get the sink capabilities when there is a load connected. I suppose that this is done by sending a message to the load and to do that I think you have to write ...
Hi,I'm trying to implement a `delay(microseconds)` function on an STM32 F745 running at 216 MHz. I want to keep it dummy and simple without involving interrupts. My strategy is as follows:-Setup TIM2 to run at 1 MHz. Since it has a 32-bit counter it ...
Hi I am trying to assign values to an array to send for an spi transaction, I declared the variable and assigned each index of the array in a loop, but when I am debugging it the array is constantly 0 for each of its elements unless I defined it as a...
