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 04:51hi,i initialize and set rtc as followint rtcInit(void){ RCC->APB1ENR1 |= RCC_APB1ENR1_PWREN; // enable PWR clock PWR->CR1 |= 0x00000100; // disable BD write protect while(0 == (PWR->CR1 & 0x00000100)); ...
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 ...
Posted on July 18, 2017 at 17:27I am using an STM32F373 and debugging with SWD. I want to use PA15 as an IO pin. When I go to configure PA15 as an output, the call to GPIO_INIT() causes a reset which disconnects the debugger. I'm not sure, but I ...
Posted on June 09, 2017 at 22:53I'm trying to set-up a STM32F091 with a battery connected straight into the VBAT pin. For the first couple times I turned on this vbat at 3v, It worked ok(no weird behavior). However, after trying to program the MCU v...
Posted on June 21, 2017 at 12:55Hello.There was a problem with the operation of the ADC with built-in thermistor and VBAT voltage.The value 4095 is always read.Here is an example of code for reading voltage VBAT: /* Configure the ADC clock */ RCC_...
Posted on July 18, 2017 at 12:05Hi,Using STM32CubeMx version 4.21.0 for STM32F765VG with KSZ8081RNA ethernet PHY (RMII mode).Ethernet is painfully slow. Received packets are dropped and transmit packets are somehow also lost.Does anyone have any gui...
