Posted on March 07, 2012 at 15:22I configure SPI2 and I2S2_ext for running I2S in fullduplex mode using DMA1_Stream4 and DMA1_Stream2. DMA1_Stream4_IRQHandler called and i2s tx is working fine, but DMA1_Stream2_IRQHandler not called at all. Please ...
Posted on June 04, 2012 at 17:54While working on I2S on STM32F407, I came across an issue I believe is a bug in silicon. I need duplex I2S, so I have configured I2S2 as Master Receiver and I2S2ext as Slave Transmitter, with outputs on port I, i.e. P...
Posted on May 10, 2012 at 17:07Hi, I am using STM32F105RB and I have a problem with an I2S master receive connection, using SPI2. I have configured SPI2 in I2S master Receiver mode, and enabled a SPI2 receive interrupt but immediately after SPI2 ini...
Posted on April 12, 2012 at 22:49Hi, I have a problem with an I2S master receive connection, using SPI2. SPI2_DR is receiving values, so the I2S is working on some level, but none of the interrupts I have set are being generated. RXNE is 1, meaning ...
Posted on August 19, 2011 at 08:32Hi,I was testing I2S interface on STM32F107 cpu. I had configured the chip to use I2S3_MCK clock as the Master Clock for the codec. I2S is set in master mode. I had set the MCKOE bit in the SPI_I2SPR register. But t...
