Hi All, I'm sitting here with a H8S/2633F cpu and I'm setting up a 16 bit TPU for reset on compare match A (TGRA). The question is: When exactly will the timer reset ? ON compare match, or the clock pulse after ?? I.e. if I set TGRA to 0x1234, what will the timer range be? A) 0x0000 - 0x1234 meaning that a loop will contain 0x1235 clock pulses B) 0x0000 - 0x1233 -> loop contains 0x1234

Hi All, SPI is more simplistic in internal IC hardware design than I2c. If the SPI data bus receive garbage (spikes or noise) you can pull the chip select high and start clocking the data in/out again. SPI has /CS chip select Clock Data out Data in I2C has Clock Data Question ======== If an I2C bus receives garbage, how does one tell a I2C receiver to "reset" and start...

Hi, .ELF to .BIN conversion is working for one set of source code , but it is not working with another set of code . I do the following for converting the .ELF to .BIN : "m68k-elf-objcopy -O binary clock.elf clock.bin". Does source code have any role in affecting the generation of .ELF to .BIN ? OR Does configuration settings of the compiler that generates the .ELF file ...

Hi, I have some queries based on the MPU Clock/Reset/Power Mode Control Registers of OMAP 5912 and 5910. Does the term "OMAP 3.2 hardware engine" mentioned in OMAP 5912 technical document refer to the term "DSP" mentioned in OMAP 5910 technical document. Pls find the snapshot of the info : In OMAP 5912 ============= ARM_RSTCT1 - MPU Reset Control 1 Register . This is a 32-bit ...

Hi, sorry if this is off-topic, but reading the datasheet of the 8253, I don't understand the sentence concerning the mode 2 and 3 : "In modes 2 and 3, if a CLK source other than the system clock is used, GATE should be pulsed immediately following /WR of a new count value" can somebody help me ? pascal

Hi folks, I need to convert TMDS to LVDS. Im sure someone has done this before, so rather than reinvent the wheel, I'd like to ask what chips are suitable for this. I need to drive a panel with 3 data and one clock pair (so I assume 18 bit?) Thanks, -Ian

Hello fella's I know I am completely out of my league with this question but I have to ask anyway. Be gentle. :-) I have built this clock because it is really cool! and it is completed up to the point of programming it. It uses 3 pic18f252 micro controllers. 1 controller is a master and 2 respond as slaves. I don't know how to do this. I think it would be like flash programming a bio...
