are two FIFO In the I2C adapter, namely tx fifo and Rx FIFO. The former is used to buffer all pending commands sent to the adapter, this includes reading from the device and writing from the device. For the adapter we are currently working on, it is the eight cmd commands, S0 ~ S7: S0: idle S1: Send start and one byte S2: write one byte S3: write one byte and send stop S4: read one byte and send an ACK S5: read one byte and send an nack S6: read one

increase the pause time. In the following example, the command uses a 9 modifier to represent an access (public) external line. Because of the comma (,) modifier, the modem delays dialing before the phone number 5551212. For example, ATD 9, 5551212 [enter] ! : Use the host to flash. Exclamation point (!) The modifier makes the modem wait (pause) for half a second, which is equivalent to holding down the switch hook key on the phone for half a second. This function is useful when transferring c

conversion value is C0-Cm, real-time numerical value is Z. Therefore, B0 corresponds to A0, BM corresponds to AM, y corresponds to X, and y = f (x ). Because of the linear relationship, the equation is Y = (Bm-B0) * (X-A0)/(Am-A0) + B0. Because of the linear relationship, the mathematical equation z = f (x) After A/D conversion can be expressed as Z = (Cm-C0) * (X-A0)/(Am-A0) + C0. Then it is easy to obtain the inverse transformation of the mathematical equation x = (Am-A0) * (Z-C0)/(Cm-C0) +

How to submit js insert row data write a dynamic insert row with js, each field is input, and the entire table is in form, submit with post, it seems that cannot be submitted. How can we get the value of each input in the js insert row? Reply to discussion (solution) The form control with the same name must be named using arrays. In this way. What is 'cannot submit '? We recommend that you carefully describe the problem. You 'd better paste the code. Post submission? Cannot submit?Are y
