Posted on July 19, 2017 at 12:50 To clear the RXNE Flag of an USART, you can either read the RDR register or set the RXFRQ flag in de RQR register. Which of these two methods will take up the least processing time? void USART2_IRQHandler(vo...
Posted on July 19, 2017 at 04:06Dear sir:What kind of functions of STM32F4 series can be limited when it is supplied by 1.8V VDD?thanks!panxiaohong#what-kind-of-functions-of-stm32f4-series-can-be-limited
Posted on July 19, 2017 at 10:46In STM32L4 SPI 1 i am use in Receive only master mode and hardware NSS signal in output mode.In that project how to control the NSS pin (chip selection pin),I am use only one slave MCU is master ex.ADC is slave....
Posted on July 17, 2017 at 09:06I was using STM32F103VET6 (LQFP) for 3 years. At this time, we found some parts' pins were dark and the showed assembly in Philippine. Last lot parts came from Korea which were fine. So we followed AN2639 document to ...
Posted on July 19, 2017 at 08:49Hello,i'm using a F103ZC to interface the external RAM IS61WV51216BLL. I used the AN 2784 as reference (Same RAM and same pin connection). For setup up of the FSMC i used the Example in the F1 SPL (for STM32F10E Eval ...
Posted on July 19, 2017 at 07:55I have lwIP working with two network interfaces: Ethernet + GSM (PPP). How must LwIP work with routing?Device receives IP-packet by Ethernet and transmits to PPP-netif.

Posted on July 19, 2017 at 04:15Dear sir:Now, I use STM32F4XX to design our product. And, I want to connect an external MCP flash(Nor flash+Psram)by FMC interface on STM32. The MCP flash means Nor flash and Psram are both in the one package.So I w...
Posted on July 19, 2017 at 00:57Hello,I am attempting to power the STM32F100RB from a battery pack, however I am unsure what needs to happen in order for this to work and the datasheet has been vague/confusing (or I'm missing something). I at first ...
Posted on July 18, 2017 at 13:51Workalot would like to obtain the MCU's ID, just like the STM32 ST-Link utility does. It reports an ID 0x413 and a 1MB Flash for my STM32F4Discovery.To be clear, I am not after the 96 bit UID (at 0x1FFF7A10) nor am I ...
