There should be no problem with the board, because when using the nk.nb0 file provided by that company, it is possible to make a nk according to the instructions of smdk2410 provided by his company. 0...
I am planning to amplify a small signal of about 5MHz, which is only a few to ten mV. I don't know how to choose a suitable op amp with an amplification factor of about 50. The op amp has a BW@Acl uni...
[backcolor=rgb(239, 245, 249)]I use a 28335 chip to control an optocoupler. The rectangular wave is normal when it passes through the optocoupler and reaches the IPM. I add 15 or 20V to the IPM module...
Question: What is the problem if the counter does not work? The boards have these chips: 74373 (02 08 10 21 07 32 175 154 138 245 573), 8155, 12887, cy7c136, W78E516B, oks1235, etc. I don't use 74193....
