Posted on June 18, 2018 at 07:16I generate a TrueSTUDIO project for STM32F042K6 to make a USB CDC VCP device using STM32CubeMX-4.23, firmware 1.9.0. Change RX/TX buffer size to 256bytes, and SYSCLK source to HSI48.Build Project OK.Debug and then cli...
Posted on June 11, 2018 at 22:16I have 746 Discovery board, I want to show whole screen JPG images with it. Applications\LibJPEG example only shows partial screen and it crashes with larger.Do you know how to use larger images with the board. There ...
Posted on October 24, 2013 at 19:44I run a program fine on bank 1. Then programmed BFB2 to 1. (BOOT0 = 0).Compile Blinky to 0x08100000 and load it. Checked the flash by stlink-util and see0000: 20000468 081001c1.Those are correspondent to the .map f...
Posted on May 01, 2018 at 23:12Is the code in HAL_PCDEx_SetTxFiFo() within stm32f7xx_hal_pcd_ex.c correct?The datasheet says:OTG device IN endpoint transmit FIFO size register(OTG_DIEPTXFx) (x = 1..5[FS] /8[HS], where x is theFIFO_number)Bits 31:16 ...
Posted on June 19, 2018 at 16:39 Dear Sir/Madam: I am using STM32F4x nucleo HAL lib, and try to set timer interrupt. It does not work. Here are the settings for timer interrupt: ..... // Timer is configured to be triggered every .05 secs. ...
Posted on October 17, 2017 at 18:03 I tested three devices all day long today. All devices are connected to the USART, but the incoming interrupt does not work at all. A program that connects the Lo Ra modules, GPS modules, and wifi mod...
Posted on May 08, 2018 at 21:37I have built and downloaded the FP_IND_PLCWIFI1 project to the NUCLEO-F401RE board using the IAR version.I am able to connect to the WIFI, but when sending a project from the ST-PLC-Android app, a failure occurs:What d...
Posted on June 08, 2018 at 21:35 I am Using the #RTC #M41T94 for keeping time on my project.Have noticed on multiple occasions that there is a significant #drift in the time keeping. Have reviewed the datasheet multiple times to check if my schemat...
Posted on June 19, 2018 at 12:10Hi All, I'm working on STM32L4 MCU in CPP project(cubeMX code that c code i convert to cpp), i have one doubt in NEW operator, i create array of pointer object and i build code no error but while debugging i got...
Posted on June 19, 2018 at 12:26 I am using STM32F103RCT6 to blink a LED which is connected to PA15 - JTDI in PU. My GPIO Configuration is like this GPIOA->CRH |= GPIO_CRH_MODE15; //Output mode, max speed 50 MHz. GPIOA->CRH &= ~GPIO_CRH_CNF...
