Posted on October 11, 2016 at 12:19First: I do not use USB MSD and FatFS at same Time, but they work on the same SD-Card. This SD-Card is connected via SDIO with 4 Bit Databus. I use a STM32L476 but I think the Problems should be identical for all S...
Posted on August 15, 2017 at 15:12 Hi, I am using a Nucleo F401RE running at 84 MHz (8 MHz XTAL PLL'd up to 84 MHz) and then using Timer 2 as a simple counter to count how long it takes to run the delays. Timer 2 is set to run at 84 MHz with n...
Posted on August 10, 2017 at 21:11We need software written that implements a STM32F407 host mode USB driver, able to connect and communicate with USB serial devices that expose multiple virtual devices such as GSM/GPRS modems or Telit.I wanted to ge...
Posted on August 11, 2017 at 22:33 I have been playing with 4bit SDIO and FatFS. I was able to get good write speeds (8-9 MB/s) but i would often get errors and the SD card lock up. No read/write. Project is CUBE 4.0 generated for the STM32...
Posted on August 14, 2017 at 07:31Greetings,I generate the project using To control the bldc motor with hall sensors interface. The configuration is as below:Refer to TIM4, which is set as the hall sensor interface, the detail configuration is as be...
Posted on July 28, 2017 at 07:56Greetings,I am rolling my own USBD DFU bootloader for an STM32F427. I have a CubeMX project reading and writing to Internal Flash. Now I need to expose the OTP memory region, similar to the System Memory USBD DFU boot...
Posted on August 13, 2017 at 14:25I have an STM32F427ZGT 1M Flash part and I see in the reference manual this statement:Bit 4 BFB2: Dual-bank Boot option byte0: Dual-bank boot disabled. Boot can be performed either from Flash memory bank 1 or fromsy...
Posted on August 12, 2017 at 08:55Hi2 questions here:1. Why do I need the osDelay(1) before netbuff_delete()? Without it I get a statistical bug/crash. 2. why do I need lines x1-x3. Without it no second connection is possible./*--------------------...
Posted on May 19, 2017 at 01:48I have a custom board that uses an STM32F415RGT6. It has USB_OTG_FS_DP on pin 45 (PA12), USB_OTG_FS_DM on pin 44 (PA11), USART1_RX on pin 42 (PA10), USART1_TX on pin 43 (PA9), plus lots of other connections.I created ...
Posted on August 11, 2017 at 11:15Hello,I am creating a project on a STM32F417IGH6 with LwIP using the CubeMX tool. The code compiles perfectly, but I cant get a connection to the Ethernet. The PHY I am using is a LAN8720A.A project that I ported fr...
