Posted on October 11, 2016 at 23:31I'm having an issue using the FMC to access the SDRAM on an IS4216400J DRAM chip. When I read back the data, it seems the values are misaligned by a half-word. For example, here's some test code I am using: __IO u...
Posted on October 12, 2016 at 14:46Hello, I was working off of TIM_PWM_Output (Peripheral_Examples from FW_V1.1.0) and would like to add UART connection to it.How do I initialize UART if using FW_V1.1.0?Thanks, Sel
Posted on August 01, 2016 at 14:02Hello,I use an STM32F030 in the current project and I need timer 1 to stop during debugging (breakpoints, execution stop). It does not matter whether the pwm outputs stop in hi or lo, they just need to stop.After se...
Posted on October 04, 2016 at 19:25HelloI've searched almost everywhere but I can't find any example of an SNMP client code. What I'm trying to do is to issue simple SNMP Get/GetNext/Walk commands from an STM32F429 (lwIP) in order to query values fr...
Posted on October 12, 2016 at 10:23Hello, Found mistakes for SYSCFG_MEMRMP register in many stm32f4 headers using last Cube F4 1.13.0 /****************** Bit definition for SYSCFG_MEMRMP register ***************/ #define SYSCFG_MEMRMP_MEM_MODE...
Posted on July 12, 2011 at 19:22Hi All,I need to put a unit into a low power mode (< 300uA), then be able to periodically wake it using either a 1Hz tick from the 32.768kHz crystal, or from a transition on any of the pins PC4 through PC7.The system ...
Posted on October 11, 2016 at 10:42I am not able to receive data with any usart (usart1, usart3) with interrupts.The RXNE interrupt never gets asserted and therefore the interrupt is never called. I have jumpered the TX/RX terminal in ''loopback'' f...
Posted on October 11, 2016 at 21:00Using an STM32L051, I am unable to generate a 32MHz system clock from from the PLL using the HSI as the clock source. I can generate up to 24MHz without trouble, but any attempt to generate higher frequencies resu...
Posted on October 11, 2016 at 19:45 Hello I send and receive data from Ethernet with cmsis library I send my data with send function each 100ms(with each timer interrupt) void send(void){ unsigned char i; unsigned long int...
Posted on October 11, 2016 at 17:45 Does KEIL use the open source tool chain such as arm-none-eabi-gcc or does it use its own custom toolchain? The reason I ask is we develop our libraries for the STM32F0 device but our libraries have to work with a...
