It's normal for the master to terminate reads with NACK rather than STOP, as it forces the slave off the bus rather than risking the bus becoming stuck in the case where the slave thinks that the master is going to read more data (see the F4 reference manual, I2C/Master Receiver/Closing the communication). This is the start of the stable review cycle for the 4. 固然,STM32 I2C硬件接口有设计不完善的地方,例如下面就是我从STM32最新的Errata sheet中总结出的,关于STM32 I2C接口设计上的一些缺陷和如何避开这些缺陷的推荐程序模型: (1)把I2C的中断优先级提升到最高 (2)把发送多于2个字节的发送与接收封装成利用DMA收发. 0 portfolio. These devices are capable of providing both USB 3. After the first I2C module makes a successful communication second module gets stuck. The FRDM-K64F is fully supported in the mbed platform, so it gets access to the free tools and SDK that provides experienced embedded developers with powerful and productive tools for building proof-of-concepts. The issues were relating to the timing and handling of retrieving data from buffer and so I had to handle the transmission and reception of all data within the I2C interrupt. It appears there are some issues using the AS3935 chip in I2C mode with the default address of 0x00. I 2 C (or I2C, for Inter-Integrated Circuit) is a form of two-line communication used to communicate most commonly between microcontrollers and peripheral ICs at a low speed in short-distance, intra-board applications. This I2C digital temperature sensor is one of the more accurate/precise we've ever seen, with a typical accuracy of ±0. Clock Problems. and use the pin for i2c. 0 @ svidosh. I2C is a real pain; the requirement to accommodate clock-stretch from the slave means you have to be bidirectional on all the lines. Re: Problems with STM32 SPI and Chip Select « Reply #21 on: May 20, 2016, 10:47:10 am » Of course i did just after reply #1 On the to-do list there is a pdf containing all the registers, bits and explanations in a compact form, a datasheet a-la rest of the world (i think i'll just be lazy and insert the additional pages from the reference. Just another thing to consider: In this ERRATA document (page 24) you can find there is a glitch in I2C analog filter which can cause BUSY flag hanging. For the reference: the same problem is described there, but the author's solution doesn't work for me - I2C busy flag strange behaviour.
