对STM32内部FLASH编程时遇到的ADC异常问题 - STM32团队...

具体到本案例,严格地讲,后来客户觉得读不到ADC的更新数据,不是因为ADC不工作,其实它一直被定时器触发转换,只是因为发生了溢出,没法正常触发DMA传输,进而无法实现ADC结果的搬运。

Flash ADC Flash ADC - Analog

用Flash 型ADC 。由于近年来VLSI工艺技术和设计技巧的进步,现在市面上出现了许多4 到10 位分辨率的 Flash型转换器。然而,要在这些转换器提供的高采样速率下成功发挥其效用,必须考虑并补偿Flash型转换

Understanding and minimising ADC conversion errors

UNDERSTANDING AND MINIMISING ADC CONVERSION ERRORS The quantization error is the error introduced because of the process of quantization. Ideally any analog input voltage can be maximum of 1/2 LSB away from its neares...

记录一个GD32E230的ADC+DMA的重大问题 - CSDN博客

文章描述了一种问题,使用ADC和DMA进行数据采集时,由于调用Flash读写函数导致ADC数据错位。 尽管正常和异常情况下的寄存器值相同且无内存越界,但问题的触发似乎与Flash操作及程序启动的偶然性有关。
