• 8051 in TTL-LOGIC
    I'm just starting on a "8051 in TTL-logic"-design. Is this ever done before? I hope to present the results so far on my site by Tuesday. Any comment is welcome.
  • UART TTL Level Communication Distance
    I am facing some embarrassing problems recently. After some trouble-shooting, I found that: We have Board-A and Board-B. Board-A and Board-B communicate to each other with a UART TTL Level Communication...
  • Trace logic level of a pin on stm32f7
    Hi, I am using keil and a stm32f7 ARM Cortex M7 based. I need to trace the logic level of a series of pins. I am interested in seeing the digital signal in time that I generate through this pins. There...
  • TTL TO RS 232
    HI, I am super confused why we need to use ttl to rs 232 conversion and rs232 to ttl conversion. please help...
  • 3.3V supply for ttl/rs232
    Hi, I find a problem when I wanted to run a ATMEGA32 with VCC supply of 3.3V, everything is okay except USART. I see that if supply voltage is 5V then USART works well. With the same ttl/rs232 module...
