STEVAL-IHI002V1

STEVAL-IHI002V1 User interface for home appliance / S-Touch™ daughter demonstration board Data Brief Features ■ 12-bit GPIO device with additional 12-channel capacitive sensing sensors ■ Interface with MCU through I²C bus. ■ Fast and accurate results at very low power consumption ) s ( ct u d o Description STEVAL-IHI002V1 r P e This demonstration board is designed to modernize or even fully replace a mechanic keyboard. The demonstration board is based on the STMPE1208S device, a 12-bit GPIO expander with an additional 12-channel capacitive sensing sensor, which is able to interface a main MCU through I²C bus. The demonstration board is designed to work as a daughter board for the STEVAL-IHI001V1 (washing machine user interface). Once plugged in, the STEVALIHI002V1 is automatically detected by the mother board, replacing the mechanic keys by a wheel, a slider and 5 buttons. t e l o ) (s s b O t c u d o r P e t e l o s b O November 2008 Rev 1 For further information contact your local STMicroelectronics sales office. 1/4 www.st.com 4 DIG5 SEG1 DIG1 DL1 DL25 INPUT 5V-30V J1 CON3 KEY 2 1 2 3 SEG2 KEY 1 DL2 SEG3 SEG4 1 2 2 3 3 TR1 SMAJ33A-TR 4 P10 TACT-2 4 3 2 P5 TACT-2 1 SEG5 3 2 SEG4 D6 1N4007 R6 10K 5% R5 10K 5% DL26 SEG3 DL3 DL27 SEG2 DL5 DL29 SEG1 DL4 DL28 SEG7 DL30 2 2 3 DL6 C1 10uF 35V 4 DIG6 C2 220pF 3 P9 TACT-2 1 4 P4 TACT-2 1 SEG8 DL8 SEG7 SEG6 DL7 SEG6 STAND ALONE DL9 SEG8 SEG5 2 DL10 DL32 2 3 2 4 8 6 SY NC COMP VCC VREF U4 L5970D 3 2 4 FB OUT 3 1 5 4 L1 33uH 10 11 12 DL17 2 R3 4K7 1% R2 15K 1% D5 1N4148 D4 1N4148 D3 1N4148 D2 1N4148 D1 1N4148 DIG5 DIG6 DIG7 VCC DIG1/LED DIG2 DIG3 DIG4 D7 STPS340U 1 P6 TACT-2 1 2 P1 TACT-2 1 4 DL13 3 P7 TACT-2 1 4 P2 TACT-2 1 DIG5 DIG6 DIG7 9 DL16 DIN/DOUT CLK STB IRQ_N DL19 + +VDD SEG5 SEG4 SEG3 SEG2 SEG1 C4 100uF 16V SEG5/KS5 SEG6/KS6 SEG7/KS7 SEG8/KS8 GND SEG1/KS1 SEG2/KS2 SEG3/KS3 SEG4/KS4 ISET KEY 1 KEY 2 DL22 DL21 SEG1 SEG2 SEG3 SEG4 21 20 19 18 16 15 14 13 DL23 ICCD ICCC RST J5 CON10A 1 3 5 7 9 J2 CON10A 1 3 5 7 9 +VDD MD2 +VDD C8 10nF ICC Programmer 2 4 6 8 10 I2C Expander I2CD 2 I2CC 4 RST 6 RST0 8 MD1 10 SEG5 SEG6 SEG7 SEG8 KEY 1 KEY 2 24 23 22 17 DL24 R4 390 1% C5 + 10uF 16V 3 4 5 7 9 R10 4K7 5% DIG2 R11 4K7 5% +VDD A1 a b c d C7 100nF +VDD 10 11 8 9 6 7 RST 8 6 1 2 10 1 2 3 4 5 A2 dp g f e PA3 PA4 RST0 I2CD I2CC DY1 Common Anode BZ1 Buzzer +VDD Q1 BC337 1 2 +VDD 14 15 16 12 13 e f g dp A2 OSC1/CLKIN OSC2 VDD VSS RESET NC ATPWM1/PA3(HS) ATPWM2/MCO/PA4(HS) ATPWM3/PA5(HA) I2CDATA/PA6(HS) I2CCLK/PA7(HS) U2 ST7FLI49MK1T6 10 2 1 6 8 AIN0/PB0 CKIN/AIN1/PB1 AIN2/PB2 VSSA VDDA R8 10K 5% R9 4K7 5% BUZ TP2 TP1 d c b a A1 +VDD MD1 MD2 GINT TINT PA2 PA3 PA4 RST0 I2CD I2CC +VDD PB7/AIN7 PB6/AIN6 PB5/AIN5 PB4/AIN4 PB3/AIN3 PC7/BREAK PC6 PC5 PC4/LTIC PC3/ICCCLK PC2/ICCDATA PC1/AIN9 PC0/AIN8 PA2(HS)/ATPWM PA1(HS)/ATIC PA0(HS) DY 2 Common Anode u d o R1 4K7 C3 22nF 4 P8 TACT-2 1 4 P3 TACT-2 1 DL11 C6 100nF DL12 +VDD 5 6 7 8 DIG1 DIG2 DIG3 DIG4 DL15 1 2 3 4 DL14 DIO CLK STB IRQ DIG7 U3 STLED316S DL18 2/4 QST s b O t e l o S-TOUCH P e INH d o r t c u ) (s s b O t e l o r P e 3 DIG3 GND 3 9 7 5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 21 20 19 18 17 29 28 27 26 25 24 23 22 32 31 30 DIG3 4 J3 CON15 DIO CLK STB IRQ BUZ ICCC ICCD MD1 MD2 GINT TINT PA2 TP4 TP3 3 4 5 7 9 1 2 3 4 5 6 7 8 9 10 R15 10K 5% A2 dp g f e J4 CON10 R14 10K 5% DIG4 R13 10K 5% +VDD R12 10K 5% +VDD A1 a b c d DY 3 Common Anode 10 8 6 1 2 Figure 1.
