Posted on June 07, 2013 at 20:17I need to interface the STM32F407 to a 1K x 8 DPRAM (7C131). The 100 pin STM32F407 package I want to use does not support nonmultiplexed address and data. I have no problem in using a latch to de-multiplex the A0-A7 f...
Posted on August 24, 2012 at 00:41stm32f4-discoveryI am impressed with the built-in 12bit adc. I want eventually to read 12 voltages at 10Hz or greater. I am going to simplify the problem to 2 channel add and expand to 12 once that is working. I rea...
