Posted on January 16, 2018 at 11:43 I am developing IoT application on OpenWRT and USB. The STM32F103C8T6 is selected. After some research, I find its USB stack (CDC/ACM device) doesn't work well in some Linux disto. The same situation also appli...
Posted on December 06, 2017 at 22:11Hello,The title says it all. There's a a mysterious delay in USB_SetCurrentMode in F7 USB LL driver (stm32f7xx_ll_usb.c V1.2.2):Does any one know the origin/need of this delay? There's no comment (or time units) a...
Posted on January 14, 2018 at 16:15HiI am working with 'stm32l433ccu6' ARM processor and I got a serious problem which cause Hard Fault Error inside my firmware. The problem arise when I run PDM_Filter_64_LSB() function from libPDMFilter_CM4F_keil.l...
Posted on November 23, 2017 at 10:10I have a custom board based on STM32F412VE that communicates with the PC via the UART1 (pin PA9 and PA10 with 100K pullup). I have problems communicating with the bootloader. Here is an oscilloscope screenshot:As ...
Posted on January 15, 2018 at 06:17Hi,I am looking for an USB host example code for STM32F215VG using Standard peripheral drivers. I tried to modify the sample code provided along with SPL driver library but facing some issues.#usb-host #stm32f215
Posted on January 11, 2018 at 12:30I'm using stm32L476 mcu and I'm trying to configure and enable a set of timers in my stm32 project using cube, hence HAL libraries. Reading datasheet I found TIM2, TIM3, TIM4, TIM5, TIM15, TIM16, TIM6 and TIM7 coul...
Posted on January 11, 2018 at 20:33I have been having an issue in my project with LWIP. The network seems to run fine, the protocols all work, but then (usually a day or two later) the stack just stops running. It seems to happen when trying to make...
Posted on January 10, 2018 at 21:55My development hardware is the Olimex P107 board (Rev D: STM32F107VCT6 MCU, LAN8710 PHY).DHCP and ping in a bare lwIP example are working fine. Now I want to combine FreeRTOS and lwIP. I'm using the latest STM32Cub...
Posted on December 12, 2017 at 08:24It seems that the cubemx doesn't let us change CUSTOM_HID_EPIN_SIZE or CUSTOM_HID_EPOUT_SIZE, and in the codes, we don't have a user defined part for this. so this cause to define it asthe default value which is 0...
Posted on January 10, 2018 at 10:54i m working on stm32f41g-eval. handshake done successfully. when my response from server is greater then 3k at that time this error come other wise mbedtls_ssl_read work fine. so please suggest me to read data of 1...
