Can the I/O pins on the HT46 series of MCUs be used as LCD drive pins?
Holtek Semiconductor - Cost-Effective A/D Type MCU SeriesThe pins on the HT46 series can be setup as either CMOS outputs or Schmitt trigger inputs, therefore they can be setup in three conditions which are, a high level output, a low level and as an input. By using an externally connected resistor divider on an I/O pin, when setup as an input, a voltage of VDD/2 can be generated. In this way a 3 common LCD configuration can be generated.
Related QuestionsAre there are limitations on using the I/O pins of the HT48 series MCUs to drive an LCD?
Holtek Semiconductor - I/O Type MCU Series FAQsBecause the I/O pins can only generate three voltage levels, namely, VDD, VDD/2 and GND voltages, therefore only 1/2 bias LCD panels can be driven. For LCD panels that require other Bias types, it is not possible to use the I/Os.
Related QuestionsCan the HT48 series of MCUs be used to implement an LCD driver?
Holtek Semiconductor - Remote Type MCU Series FAQsYes they can, but the implementation will be limited to 1/2 bias with pull-high and pull low resistors connected to the I/O pin. Three different voltage levels can then be obtained by setting up the pin as an output and setting it high, setting up the pin as an input, and setting up the pin as an output and setting it low. The HT48XA series of MCU devices all contain a 2.0V LVR option. Under most operating conditions it is recommended that this option is selected.
Related QuestionsFor HT46 series MCUs, how to adjust the PWM frequency on port D?
Holtek Semiconductor - Cost-Effective A/D Type MCU SeriesFor HT46 series MCUs, the PWM frequency is derived by calculating fsys/256, in other words, once the system clock is selected, the PWM frequency is therefore fixed. Users can only adjust the PWM duty through the PWM register.

Related QuestionsWhat JStamp pins are used in Flash programming?
JStamp(tm)IOC4/FA0 (JStamp pin 15) and IOC5/FA1 (JStamp pin 14) are used both by the SPI port and flash programming on JStamp. IOC4 is the SPI MOSI signal and IOC5 is the SPI MISO signal. During flash programming IOC4 is Flash Address 0 and IOC5 is Flash Address 1. Since JStamp can never be performing SPI access while it is programming flash, there should be no problem sharing these signals. However, you need to be sure that your external hardware does not drive these signals during flash programming.

Related QuestionsHow many O-Sox can be used per well?
Adventus Group - Environmental Remediation FAQsAll O-Sox must be placed below the groundwater table and they should be within the screened interval. The wet weight of each 2-inch and 4-inch O-Sox unit (3-ft long canister and sleeve) is about 5 and 16 lbs, respectively. We therefore recommend a maximum linkage of five 2-inch diameter systems (15 ft screened interval; 25 lbs) or three 4-inch diameter systems (9 ft screened interval; 48 lbs). Up to three sets of linked O-Sox units can be used for wells with longer screen lengths.
Related QuestionsHow Far Should I Drive Non-Insulated Pins into Wood?
FAQTo full depth if possible. However, at moisture levels below 10%, it is usually sufficient to make good, positive contact with the wood. At higher levels of moisture and especially if you have a steep gradient, full penetration is a must. Otherwise you can have discrepancies between meter readings and actual moisture content of as much as 5 or 6 points, especially in the range above 20 percent. For best results in such cases, use insulated pins.
