How to Correctly Select the CPU of IIC Bus Color TV-EEWORLD

Collect

The CPU of IIC bus color TV is different from that of ordinary remote control color TV. The control software of the whole machine must be written into it. Therefore, when replacing the CPU, not only the hardware model but also the software version should be the same, otherwise the machine will not work. For example, the CPU models used by Konka T2988P color TV are TMP87PM36N and TMP87CK36N. After the former is replaced, the parameters must be written according to the agreed procedure using the factory-specific remote control before it can be used, while the latter has the software parameters solidified and can be used directly, so the latter can be used to directly replace the former without writing parameters again.

In addition, Konka T2988N color TV CPU also uses TMP87PM36N, and its software number is R0605, which is the same as the CPU model of T2988P model, but different in software, and the two are not interchangeable. This situation also exists in Konka T3888, T3488, and T2998 series machines, but no matter which of the above models, as long as the suffix is P instead of N, the original CPU can be replaced with TMP87CK36N. In addition, the current TV product models also have some characters and numbers at the end, such as F25, F19, etc. These are related to the chip software status used, so pay attention to it during maintenance, otherwise the door-to-door maintenance will be affected due to insufficient preparation of components.

STM32 serial port is suspended, causing CPU to continuously enter the interrupt function

When the STM32 serial port is enabled for interrupt, the CPU will continuously enter the serial port interrupt service function when the serial port is unconnected (i.e., no peripherals are connected). And the received data is 0. When you connect the peripheral, everything is OK. void USART2_IRQHandler(void) {

CPU reads and writes memory (II. Data bus, control bus)

2. Data Bus The data transmission between CPU and memory or other devices is carried out through the data bus. The number of pins of CPU data bus determines the number of bits that can be transmitted at one time. Because the data bus connection mode is parallel port, 8 pins can transmit 8 bits, i.e. 1 byte, at one

19-year-old boy reshapes CPU, reduces computer power consumption by 80%

Thomas Sohmers believes that even a company as powerful as Intel, which ships hundreds of millions of chips every year, has weaknesses. In his opinion, Intel's chips consume too much energy. In his startup Rex Computing, Sohmers is studying another way to design chips that only use 20% of the power required by Intel.
